Abstract
PURPOSE: To obtain a sharp cut end by a method wherein when a composite material used for the siding board or the like of buildings is cut a lining and a core material are cut with thin upper cutter edges at their front and back and as the front and back cut ends are shielded another thick edge is advanced between these upper edges.
CONSTITUTION: In order to cut a composite material composed of hard surface material 3, foamed core material 9 and soft lining material 5, when a feed length of the composite material fed continuously out of a production apparatus approaches to an intended length, a carrier 21 is moved with this feed speed, the 1st thin edge 23 arranged at the front and back of the carrier 21 is let to fall, the lining material 5 and the core material 9 are sheared by a pair of edges 23 without breaking, crushing and the cut ends at their front and back are shielded by the 1st edge 23. Then, the 2nd thick edge 24 arranged between the front and the back 1st edges 23 is let to fall to cut the surface material 3. At this time, the deformation of the cut ends of the lining material 5 and the core material 9 is prevented by the shielding action of the 1st edge 23 and the surface material 3 is cut securely.
